Writing Deborah Heiser, PhD: The Mentorship Edge, Finding Purpose and Building Your Legacy

Founder/CEO/Author

I'm Deborah Heiser, PhD, an Applied Developmental Psychologist and coach specializing in midlife, aging, and the science of purpose across the lifespan. I'm the founder of Mental Mapping and My Legacy Tree. These are platforms designed to help people understand their impact, track personal growth, and intentionally shape the legacy they leave behind. I'm also the author of The Mentorship Edge, a contributor to Psychology Today and Substack, and the former Founder and CEO of The Mentor Project, a nonprofit I led for eight years focused on connecting individuals through mentorship. I bring a research-backed but highly practical perspective to conversations about aging. I talk about aging not as decline, but as a powerful stage of expansion, meaning, and contribution. I speak about why we're inherently wired to mentor, how to measure and map personal impact over time, and how mental health screening can be integrated into everyday life to support long-term wellbeing. My work sits at the intersection of psychology, technology, and purpose, and I love helping audiences rethink what it means to live a meaningful, impactful life at any stage.
